PATENT orrice SHERLEY C. TURNER, F ROSEDALE, WEST VIRGINIA WINDING ATTACHMENT Application filed August 16, 1927. Serial No. 213,325.

This inventionrelates to a winding attach- I mentfor a band wheel crank of a well drilling rig, and it is. an object of the invention ,to provide an attachment of this kind which, swheninapplied position,joperates to effect a winding up of the usual measuring line or I torpedo line upon rotation of the band wheel. Another Object of the invention is to provid e an attachment of this kind which, when 10 in applied position, has relatively adjustable part'swhereby the axial center of the winding reel carried'by' the attachment may be brought into alignment with the axis of the V band wheel whereby the desired rotation of i the winding reel may be accomplished with the'elimination of wabbling.

L The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved, winding attachment for a band wheel crank of a well drilling 'rigwhereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous forth. a 1 ,The novel features of my invention will hereinafter be definitely claimed.

'In order that my invention may be the better understood, I will now, proceed to describe the same with reference to the accompanying drawing, wherein Figure l is a fragmentary. view in top plan ing, C denotes the conventional crank associated with the band wheel of an oil drilling rig and which is provided at spaced points therealong with the usual openings 1. These openings generallyprovide for the, requisite for use, .as will be hereinafter more fully set As disclosed in the accompanying drawconnection with said crank of the usual pitman for operating the walking beam.

In the drilling of deep wells one of the most difiicult operations in connection therewith is the withdrawing or lifting out of the measuring line or the torpedo line and especially in View of the fact that it isnow the general practice to operate the rigs with explosive engines. I

In order to provide for the raising 0r liftting of such lines, I provide an attachment for use in connection with the band wheel crank.

lt iy improved attachment, as herein dis- 7 closed, comprises an elongated rigid member 2 of desired dimensions provided at one end with acylindrical extension 3 adapted to be inserted through one of the openings 1 of the'crank C, preferably the innermost of such openings although I do not wish to be understood as limiting myself in this respect. Immediately 'a'dgacent to the inner end of the extension 3 the member 2 is provided with a shoulder 4i adapted to abut the outer face of the crank C and threaded upon the free end portion of the extension 3 is a holding nut 5 or the like. By this means the member 2 is effectively attached to the crank C and extending outwardly therefrom at right angles.

' It often occurs that the opening 1 through which the extension 3 is disposed is of a diameter in excess of the diameter of the extension 3 and under such conditions a sleeve or bushing 6 is first arranged within the selected opening 1 and through which the extension 3 is disposed.

The outer end portion of the member 2 has opposite faces provided thereacross with the grooves or channels 7 which snugly receive the spaced arms 8 extendingoutwardly from an end portionof an elongated bearing member 9.' These arms 8 have disposed lengthwise thereof the slots 10 through which is directed a clamping medium 11 also disposed through an opening 12 arranged at the central portion of the channels or grooves 7. The clamping means, as herein disclosed, embodies a' conventional bolt and nut.

By this mounting of the bearing member disposed therethrough an opening 14 extend-' ing in the same general direction as the memher 2 and through which is adapted to be directedan end portion of the arboror shaft 15 for a winding reel R; This shaft or arbor 15 is held to the bearing member 9 by the nuts 16 or the like threaded on such shaft or arbor 15 and engaging opposite faces of the bearing member 9.

Thereel R is of a type now generally employed and is normally free to rotate upon its shaft or arbor 15 but is locked or held against rotation with respect to the shaft or arbor 15 upon propermanipulation of the Well known clutching element 17.

W'hen it is desired to raise or lift a measuring line or a torpedo line, the pitman for the walking beam of the drill rig is disconnected from the crank C and my improved attachment, or more, vparticularly the member 2 thereof, selectively engaged through one of theopenings 1 of the crank C, preferably the innermost of. such openings. The bearing member 9 is then adjusted as afforded by the slots 10 in the arms 8 to bring the shaft or arbor 15 of the reel R in alignment with the axial center of the winding reel R. The clutching element is then adjusted to lockv the reel to the arbor or shaft 15 so that upon requisite rotation of the band wheel the reel R will be caused to rotate about an axis coincident with the axis of the band Wheel, thus assuring a true rotation of the reel R free of wabble or such other eccentric movement which would'have a tendency to materially interfere with the requisite winding of the measuring line or torpedo line in lifting or raising the same from within a well.

' The opening 14 of the member 9 has fitted therein a sleeve or bushing 18 held against displacement by a binding screw 19 or the like. Thissleeve or bushing 18 is used to advantage under such conditions where the portion of the shaft or arbor 15 disposed through the opening 14 is of a diameter less than the diameter of such opening.

From the foregoing description it is thought to be obvious that a winding attachment for a band wheel crank of a well drilling rig constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious thatmy invention is susceptible of some change and modification without departing from the principles and spirit thereofand for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim I 1. In combination with a rotating member having a crank, an attachment therefor comprising a rigid member, means for securing the member to the crank to extend outwardly therefrom at right anglesthereto, a rigid bearing member disposed substantially at right angles to saidfirst. named member, said bearing at one end portion having spaced arms between which 18 arranged the outer end portion of the first named member, said end portion of the first named member hav ing grooves in oppositefaces receiving the arms of the bearing member,said arms having slots, a clamping means carried by the first named member and coacting with the bearing member for adjustably connecting the bearing member with said first named member, said clamping means being disposed through the slots of the arms, and a driven element operatively engaged with the bearing member. a f

2. The combination with a rotating member having a crank, of an attachment comprising an elongated rigid member, means for connecting one end of the member at any one of a series of points longitudinallyof the crank to secure the member at right angles thereto, a bearing member comprising a rigid arm, a driven member including 7 a shaft,

means for removably connecting one end of v the bearing member to said shaft to position at right angles thereto, said shaft being an signature.
